Under which condition does Medicare become the secondary payor?

Medicare becomes the secondary payer when a Medicare Secondary Payer condition applies. This situation occurs when beneficiaries have other insurance coverage, which can include employer-sponsored plans, workers' compensation, or liability insurance. In these cases, the primary insurance is responsible for covering the majority of medical costs before Medicare will pay for any additional eligible expenses.

This is crucial for medical billing and patient access roles, as understanding the hierarchy of insurance coverage helps ensure that claims are submitted correctly and that patients understand their financial responsibilities. By knowing when Medicare acts as a secondary payer, professionals can navigate the complexities of patient billing and avoid delays in payment, ensuring a smoother process for both the healthcare provider and the patient.
